Abstract

In this work, the electrical transport properties of metallic La_0·67Sr_0·33MnO₃ and insulating La_0·5Sr_0·5MnO₃ films were manipulated by ferroelectric polarization of BiFeO₃ and light illumination at 40 K. Compared with BiFeO₃/La_0·67Sr_0·33MnO₃ heterostructure, the BiFeO₃/La_0·5Sr_0·5MnO₃ heterostructure shows more obvious photoconductivity response when switching the out-of-plane polarization direction of BiFeO₃, as the downward polarized state of BiFeO₃ and light illumination both promote the transition towards the ferromagnetic metallic phase of La_0·5Sr_0·5MnO₃. These results would be helpful for the practical application of all oxide heterostructures in photoelectric devices.
